Windows

Download the ".msi" installer file and double click to open.

On Windows 10, sometimes, Microsoft Edge does not let you download installers from unknown sources for security purposes (the warning comes up after the download finishes); you will need to select "Keep File" and follow prompts.

If a security prompt comes up after opening the installer, click on "Run Anyway".

Follow prompts for installation.

Linux

Linux users have a CaPTk AppImage available called CaPTk_${Version}.bin.

To run the AppImage, first open a terminal in the same directory as the .bin file.

You will want to make sure it is runnable as an executable with the following command:

chmod +x CaPTk_${Version}.bin

To install CaPTk to the current directory where the AppImage was downloaded, run the following command:

./CaPTk_${Version}.bin

To specify a preferred directory to install CaPTk, run the following command:

./CaPTk_${Version}.bin --target {path_to_preferred_directory}

Follow prompts to install.

macOS

Users will download the ".pkg" file from NITRC; double-click the file.

If there is a window saying that this is an "unidentified developer", hit "OK" and then go to "System Preferences > Security and Privacy" and you need to click on "Open Anyway" beside the "CaPTk_$version.pkg" (this will prompt for your password).

Double click on the pkg file and click on "Open". This will guide you through the installation screen with licensing information.

Before installation begins, you may be prompted for your password again.

You will find CaPTk under your "Applications" folder and you can delete the disk image.
